Processed ship-based Multibeam Sonar Data (version 2) acquired near the Central America Subduction Zone during the Melville expedition VANC02MV (2002)

This data set was acquired with a ship-based SeaBeam 2000 Multibeam Sonar system during Melville expedition VANC02MV conducted in 2002 (Chief Scientist: Dr. Andrew Fisher). These data files are of MBSystem format and include Swath Bathymetry data and were processed by the GMRT Team using the open source MB-System multibeam sonar processing software. These data are included in the GMRT Synthesis, version 1. Data were acquired as part of the project(s): TicoFlux II: The Thermal State of 20-25 Ma Lithosphere Subducting at the Costa Rica Margin; Implications for Hydrogeology, Fluxes, and the Seismogenic Zone, and funding was provided by NSF grant(s): OCE00-01892, OCE00-01941, OCE00-01944, and OCE00-02031.
